摘要: 应用电子克隆的方法获得了玉米的一个Pti1(Pto-interacting 1)同源基因的全长cDNA,命名为ZmPti1-1(GenBank 接受号为EF1803)。推断ZmPti1-1蛋白含有362个氨基酸,分子量为39.00 kDa,pI为8.14,包含蛋白激酶催化结构域保守的11个亚结构域。在水杨酸 (Salicylic acid,SA)、甘露醇、氯化钠、脱落酸(Abscisic acid,ABA)和4℃低温的诱导下,ZmPti1-1在玉米幼苗叶片中的表达量明显上调。同时,在玉米不同发育时期、不同组织器官内,ZmPti1-1的表达水平也有很大差异,在子房中表达量最高,在雄蕊中检测不到表达。试验结果表明,ZmPti1-1是一个玉米类Pti1 基因,响应生物胁迫和非生物胁迫的诱导。

Abstract: One full-length cDNA encoding a Ptil(Pto- interacting 1) homologue was isolated from maize through in silico cloning and named as ZmPtil-1.The predicted ZmPtil-1 protein has 362 amino acids with an est imated molecular mass of 39. 00 kDa and an isoelectric point of 8. 14 The putative kinase catalytic domain of ZmPtil-1 contains the 11 subdomains that are typical in protein kinase. ZmPtil-1 expression was up-regulated obviously by salicylic acid,mannitol, NaCl, absicic acid and low temperature(4) in young leaves of maize. Furthermore, ZmPtil-1 displayed different expression patterns in different growth stages and tissues and was most abundant in ovaries, but was undetectable in tassels. These results demonstrated that ZmPtil-1 is a maize Ptil- like gene and responds to biot ic and abiotic stress signals.
